A source tells New York Post gossip column Page Six, "Sofia was confiding in friends at the ball that she and Nick have split. They have been fighting a lot recently and have been on the brink of splitting many times. It is not yet clear if they are over for good, but they are done as a couple for now."

Vergara, who has a teenage son called Manolo from a previous relationship, recently revealed Loeb wanted to start a family with her, but she was considering freezing her eggs as she didn't feel ready to have another child.

She said, "We have a very happy relationship... Nick wants babies. Imagine me, again with a baby, when Manolo is 20! I guess eventually I'll do it - for love."
